Bicyclic thiazole compounds

ABSTRACT

The present invention relates to novel bicyclic thiazole compounds that inhibit Traf2- and Nck-interacting kinase (TNIK), and as such are useful as TNIK inhibitors administered to cancer patients, especially to solid cancer patients such as colorectal cancer, pancreatic cancer, non-small cell lung cancer, prostate cancer or breast cancer. The bicyclic thiazole compounds are showed by a next formula (I). (wherein R 1 , R 2 , R 3  and Q are as defined in the specification), or a pharmaceutically acceptable salt thereof.

FIELD OF THE INVENTION

The present invention relates to novel bicyclic thiazole compounds that inhibit Traf2- and Nck-interacting kinase (TNIK), and as such are useful as TNIK inhibitors administered to cancer patients, especially to solid cancer patients such as colorectal cancer, pancreatic cancer, non-small cell lung cancer, prostate cancer or breast cancer.

BACKGROUND OF THE INVENTION

Wnt proteins constitute a large family of secreted glycoproteins that activate signal transduction pathways to control a wide variety of cellular processes such as determination of cell fate, proliferation, migration, and polarity. Wnt proteins are capable of signaling through several pathways, the best-characterized being the canonical pathway through β-catenin (Wnt/β-catenin signaling). Deregulation of Wnt/β-catenin signaling is frequently found in many human cancers like colorectal cancer, pancreatic cancer, non-small cell lung cancer, prostate cancer, breast cancer, and many others.

TNIK is known as one of STE20 family kinases that activates the c-Jun N-terminal kinase pathway and regulates the cytoskeleton. Recently, TNIK was identified as one of 70 proteins immunoprecipitated commonly with anti-TCF4 (T-cell factor-4) and anti-β-catenin antibodies in two colorectal cancer cell lines DLD1 and HCT-116 (Shitashige M, et al., Gastroenterology 2008, 134:1961-71). Recent studies has been shown that TNIK plays critical roles in canonical Wnt signaling pathway, and therefore TNIK can be a promising target to ablate aberrant Wnt signaling in tumors (Shitashige M, et al., Cancer Res; 70(12); 5024-33 (2010)). Namely, small interfering RNA targeting TNIK inhibited the proliferation of colorectal cancer cells and the growth of tumors produced by injecting colorectal cancer cells s.c. into immunodeficient mice.

Evaluation methods for utility of the present invention which is the screening of an anti-cancer agent have already been described in WO 2009/104413 filed by the present inventors. WO 2010/64111 filed by the present inventors discloses novel aminothiazole derivatives as potent TNIK inhibitors and the effects of TNIK inhibitors on the transcriptional activity of the β-catenin and TCF4 complex. However, it has not been disclosed that thiazole compounds having bicyclic structures of the present invention are useful as TNIK inhibitors until now.

SUMMARY OF THE INVENTION

This invention provides novel bicyclic thiazole compounds that inhibit TNIK, and as such are useful as TNIK inhibitors administered to cancer patients, especially to solid cancer patients such as colorectal cancer, pancreatic cancer, non-small cell lung cancer, prostate cancer or breast cancer.

The following general reaction schemes detail the synthetic approaches to the bicyclic thiazole compounds disclosed herein. Compounds of formula (I) disclosed herein can be prepared as shown in Schemes 1-7 and as illustrated in the Examples by using standard synthetic methods and the starting materials, which are either commercially available or can be synthesized from commercially available precursors using synthetic methods known in the art, or variations thereof as appreciated by those skilled in the art.

Although these schemes often indicate exact structures, those skilled in the art will appreciate that the methods apply widely to analogous compounds of formula (I), by being given appropriate consideration to protection and deprotection or reactive functional groups by methods standard to the art of organic chemistry. For example, hydroxy groups, in order to prevent unwanted side reactions, generally need to be converted to ethers or esters during chemical reactions at other sites in the molecule. The hydroxyl protecting group is readily removed to provide the free hydroxy group. Amino groups and carboxylic acid groups are similarly derivatized to protect them against unwanted side reactions. Typical protecting groups and methods for attaching and cleaving them are described fully by T. W. Greene, Protective Groups in Organic Synthesis 3rd Edition, John Wiley and Sons, Inc., New York (1999).

Each variable in the following schemes refers to any group consistent with the description of the compounds provided herein. Tautomers and solvates (e.g., hydrates) of the compounds of formula (I) are also within the scope of the invention.

Any compound of any formula disclosed herein can be obtained using procedures provided in the reaction Schemes, as well as procedures provided in the Examples, by selecting suitable starting materials and following analogous procedures. Thus, any compound of any formula disclosed or exemplified herein, can be obtained by using the appropriate starting materials and appropriate reagents, with the desired substitutions, and following procedures analogous to those described herein.

Compounds of formula (I) wherein R² is a hydrogen atom, are generally synthesized by the formation of the amide from 5-aminothiazole intermediate (II) and an acid chloride (III-a), as shown in Scheme 1:

wherein R¹, R³, and Q are the same as defined in the formula (I).

The same type of amide-coupling reaction may be done with a carboxylic acid (III-b) under general amide coupling conditions such as 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC), hydroxybenzotriazole (HOBT) and a base such as diisopropylethylamine or triethylamine to afford the compounds of formula (I) wherein R² is a hydrogen atom.

In another approach, compounds of formula (I) may be prepared from the ester intermediate (IV) by a direct aminolysis with amines, as shown in Scheme 2:

wherein R¹, R², R³, and Q are the same as defined in the formula (I).

The aminolysis reaction is carried out by using a neat amine solution or an amine in an alcohol solution in presence of a solvent such as THF, or dioxane. The reaction is stirred and heated in a sealed tube at a temperature from 80° C. to 150° C., for 1-24 hours, preferably under microwave irradiation at 80° C. for 150 minutes using a microwave synthesizer.

An alternative route as shown in Scheme 3, compounds of formula (I) can be made by N-alkylation of compound of formula (I) having R² being hydrogen using well-known synthetic route such as reductive alkylation or alkylation with alkyl halides in case the functionalization of the molecule is compatible with this type of reactions.

wherein R¹, R², R³, and Q are the same as defined in the formula (I) and X is a halogen selected from Cl, Br and I.

The compounds represented by the formula (II) in Scheme 1, which are used as starting materials of the amide-coupling reaction, may be prepared in a similar manner as described by Cook et al. (J. Chem. Soc. 1949, 3001). For example, the compounds represented by the formula (II) may be prepared by the Scheme 4 below:

wehrein R¹ and R³ are the same as defined in the formula (I).

Thus, a mixture of isothiocyanate (V) and 2-amino-2-cyano-N-alkylacetamide is stirred in a suitable solvent such as ethyl acetate or ethanol, and heated to reflux condition for 0.5-2 hours to give the compounds represented by the formula (II).

The isothiocyanate (V) may be commercially available, or may be prepared from the corresponding amine by the methods well known in the field of organic synthesis, such as a thiophosgene treatment. The isothiocyanate (V) also can be prepared from the corresponding halides with silver (I) thiocyanate in a similar manner as described by Zhong et al. (Tetrahedron Letters, 47(13), 2161-2164 (2006)).

The ester intermediate (IV) may be prepared via a palladium-catalyzed reaction with an amine (VII) and 2-halogeno-thiazole compound (VI), as shown in Scheme 5:

wherein R¹, R², and Q are the same as defined in the formula (I) and X is a halogen selected from Cl, Br and I.

These Buchwald/Hartwig type reactions are well-known to those skilled in the art and are performed in inert solvents such as toluene, THF or dioxane and involve a palladium catalyst such as tris(dibenzylideneacetone)dipalladium (0), tetrakis(triphenylphosphine)palladium (0), palladium (II) acetate, and a base such as sodium, potassium or cesium carbonate, and a ligand such as 4,5-Bis(diphenylphosphino)-9,9-dimethylxanthene (XANTPHOS). The same type of palladium-coupling reaction may be done with a corresponding halogeno-aromatic/heteroaromatic compound and a corresponding 2-aminothiazole analog to give the same desired aminothiazole intermediates (IV).

The compound represented by the formula (VI) may be prepared by the Scheme 6 below:

wherein Q are the same as defined in the formula (I) and X is a halogen selected from Cl, Br and I.

Thus, the compound represented by the formula (VI) may be synthesized by the formation of the amide from 5-aminothiazole intermediate (VIII) and an acid chloride (III-a). The same type of amide-coupling reaction may be done with a carbxylic acid (III-b) under general amide coupling conditions such as EDC, HOBT and a base such as diisopropylethylamine, or triethylamine.

The compound represented by the formula (VIII) may be prepared from 5-aminothiazole-4-carboxylic acid ethyl ester by the Scheme 7 below:

wherein X is a halogen selected from Cl, Br and I.

5-Aminothiazole-4-carboxylic acid ethyl ester is prepared according to the procedure described by Golankiewicz et al. (Tetrahedron, 41 (24), 5989-5994 (1985)). Thus, commercially available ethyl cyano (hydroxyimino)acetate is treated with sodium dithionate in sat. sodium bicarbonate aqueous solution to give ethyl 2-amino-2-cyanoacetate, which is then converted to the corresponding formamide with acetic formic anhydride. Subsequently, the obtained ethyl 2-cyano-2-formamidoacetate is treated with Lawesson's reagent, followed by treating with a halogenation reagent such as NCS, NBS to give the desired product.

The invention is further defined in the following Examples. It should be understood that these Examples are given by way of illustration only. From the above discussion and this Example, one skilled in the art can ascertain the essential characteristics of this invention, and without departing from the spirit and scope thereof, can make various changes and modifications to the invention to adapt the invention to various uses and conditions. As a result, the present invention is not limited by the illustrative examples set forth herein below, but rather defined by the claims appended hereto.

In accordance with the present invention, the bicyclic thiazole compounds (I) or a pharmaceutically acceptable salt thereof show the TNIK inhibitory effects (Test Example1) and a remarkable antiproliferative activity (Test Example2).

Therefore, the bicyclic thiazole compounds may be used as a pharmaceutical composition (for example an anti-tumor agent) in the form of a conventional pharmaceutical preparation for an oral or parenteral administration such as intravenous drip injection.

The preparation for oral administration includes solid preparations such as tablets, granules, powders, capsules, and liquid preparations such as syrups. These preparations can be prepared by a conventional method. The solid preparations can be prepared by using conventional pharmaceutical carriers, such as lactose, starch such as cornstarch, crystalline cellulose such as microcrystalline cellulose, hydroxypropyl cellulose, calcium carboxymethylcellulose, talc, magnesium stearate, etc. Capsules can be prepared by capsulating the granules or powders thus prepared. Syrups can be prepared by dissolving or suspending the bicyclic thiazole compounds in an aqueous solution containing sucrose, carboxymethylcellulose, etc.

The preparation for parenteral administration includes injections such as intravenous drip injection. The injection preparation can also be prepared by a conventional method, and optionally may be incorporated in isotonic agents (e.g. mannitol, sodium chloride, glucose, sorbitol, glycerol, xylitol, fructose, maltose, mannose), stabilizers (e.g. sodium sulfite, albumin), preservatives (e.g. benzyl alcohol, methyl p-hydroxybenzoate).

The bicyclic thiazole compounds are effective for the treatment of tumors, especially solid tumors such as colorectal cancer, pancreatic cancer, non-small cell lung cancer, prostate cancer or breast cancer.

The dose of the bicyclic thiazole compounds may vary according to the severity of the diseases, ages and body weights of the patients, dosage forms and the like, but is usually in the range of 1 mg-1,000 mg per day in an adult, which may be administered once or by dividing into two or three times by the oral or parenteral route.

Preparation of Recombinant Human TNIK (N-Terminal Segment):

A cDNA encoding the N-terminal segment (TNIK_N, residues 1-314) containing the kinase domain of human TNIK (NM_(—)015028.1) was amplified from cDNA mixture synthesized from human tissue (Biochain) by PCR using the following primers.

Forward primer, 40 nucleotides including a EheI site (described as SEQ ID NO.1 in “Preparation of recombinant human TNIK (N-terminal segment)” of WO 2010/064111 (P.29))

Reverse primer, 42 nucleotides including a NotI site (described as SEQ ID NO.2 in “Preparation of recombinant human TNIK (N-terminal segement)” of WO 2010/064111(P.29)).

The cDNA was subcloned into baculovirus transfer vector pFastBac_GSTb that includes protease cleavage site and glutathione S-transferase purification tag (GST-tag). The plasmid was purified and the insertion of the pFastBac_GSTb-TNIK_N was confirmed by DNA sequencing. Then E. coli DH10Bac competent cells were transformed with the plasmid to prepare the recombinant bacmid according to the instructions for the Bac-to-Bac™ baculovirus expression systems (Invitrogen). The Sf9 cells were transfected with the recombinant bacmid containing pFastBac_GSTb-TNIK_N using Cellfectin Reagent (Invitrogen) in SF-9001I serum free media (Invitrogen). The viral supernatant was collected from the medium 72 h after transfection. The virus was amplified three times by infecting actively growing Sf9 or Sf21 cells in Grace's insect media (Invitrogen) supplemented with 10% FCS and an antibiotic-antimycotic reagent (Invitrogen) for 72 h at 27° C. in T-flask or roller bottles. The titer of amplified TNIK_N virus was estimated at 2.36×10⁸ pfu/ml by using BacPAK™ Baculovirus Rapid Titer kit (Clontech).

Log-phase Sf21 cells (2×10⁶ cells/ml) in the Grace's insect media were infected with the recombinant baculovirus at MOI of 3.0 and incubated in roller bottles (250 ml media per bottle) for 72 h at 27° C., after which, the cells were collected by centrifugation, and the cell pellet washed with cold PBS and kept at −80° C. until purification. The following purification procedures were carried out at 4° C. The frozen cells were thawed on ice and lysed in lysis buffer (50 mM Tris-HCl, pH 7.5, 150 mM NaCl, 1% Nonidet P-40, 5 mM DTT, 0.5 mM EDTA, 0.5 mM EGTA) supplemented with 1 mM phenylmethansulfonylfluoride, 2 μg/ml leupeptin, 2 μg/ml aprotinin, 1 mM NaF, 100 μM sodium orthovanadate, and 1 μM cantharidin by sonication. The suspended lysate was cleared by centrifugation at 9000g for 20 min and the supernatant was incubated for 1 h with glutathione Sepharose beads (GE Healthcare). The beads were suspended in buffer-H (50 mM Tris-HCl, pH 7.5, 1 M NaCl, 1 mM DTT, 0.5 mM EDTA, 0.5 mM EGTA and 0.05% Brij35) and washed with buffer-H followed by buffer-L (50 mM Tris-HCl, pH 7.5, 150 mM NaCl, 1 mM DTT, 0.5 mM EDTA, 0.5 mM EGTA, 0.05% Brij35) in an Econo-pack column (BIO-RAD). The bound TNIK_N was eluted with elution buffer (50 mM Tris-HCl, pH 8.0, 150 mM NaCl, 1 mM DTT, 10% glycerol, 0.5 mM EDTA, 0.5 mM EGTA and 5 mM reduced glutathione). The eluted fractions were collected and determined the protein concentration by Bradford reagent (BIO-RAD). The TNIKN fractions were pooled and desalted using 10DG column (BIORAD) equilibrated with the storage buffer (50 mM Tris-HCl, pH 7.5, 150 mM NaCl, 1 mM DTT, 10% glycerol, 0.05% Brij35). The purified TNIKN was characterized by electrophoresis using 4-20% polyacrylamide gels and matrix-assisted laser desorption/ionization reflection time-of-flight (MALDI-TOF) mass spectrometry on a Voyager-DE RP MALDI/TOF (Applied Biosystems). TNIK_N was confirmed by the molecular weight and. MASCOT Peptide Mass Fingerprint.

Kinase assay:

The kinase assays were conducted in a 20 μl volume using 384-well plates (Greiner). The reaction mixture consists of compound or vehicle (1% DMSO), 0.08 ng/μl TNIK_N, 1 μM FITC-labeled substrate peptides, including E-aminocaproic acid and 7 amino acids (described as SEQ ID NO.3 in “Kinase assay of TEST EXAMPLE 1” of WO 2010/064111(P.31)), 20 mM Hepes, pH 7.5, 0.01% Triton X-100, 5 mM MgCl₂, 25 μM ATP and 2 mM DTT. As blank, TNIK N was excluded from the reaction mixture of vehicle (1% DMSO). The kinase reaction was carried out 1 h at room temperature and terminated by addition of 60 μl of the termination buffer (127 mM Hepes, pH 7.5, 26.7 mM EDTA, 0.01% Triton X-100, 1% DMSO and 0.13% Coating Reagent 3 (Caliper Life Sciences)). The amount of unphosphorylated and phosphorylated FITC-labeled substrate peptides was detected by Mobility Shift Micro Fluidic Technology (Caliper LC3000 System, Caliper Life Sciences). The kinase activity of TNIK_N was defined as P/(P+S) (P: peak height of the phosphorylated FITC-labeled substrate peptide; S: peak height of the FITC-labeled substrate peptide). Inhibition of the compounds was calculated as follows; inhibition (%)=(1−(A−C)/(B−C))×100 A: the mean P/(P+S) of compound wells; B: the mean P/(P+S) of vehicle wells; C: the mean P/(P+S) of blank wells. The IC50 values of the compound against the kinases were calculated from regression analysis of the log-concentration-inhibition curves.

The human colon cancer cell line HCT-116 was seeded at 600 cells/well in 96 well-plate (ThermoFisher) using RPMI medium containing 2 mM L-glutamine (Invitrogen) supplemented with 10% FCS (Invitrogen) and 1% penicillin/streptomycin (Sigma) and maintained at 37° C., 5% CO₂ and 100% humidity. The following day, old medium was withdrawn and the fresh medium was added. Initial numbers of cells were counted before adding compounds. Then cells were treated in duplicates with compounds (a half-logarithmic serial dilution from 10 μM). Eight untreated control wells were incubated in each plate. After 72 hours of treatment, cells were fixed with 2% paraformaldehyde, and the nucleus were stained with Hoechst 33258 (Invitrogen). The numbers of cells were counted with ArrayScan™ VTI (ThermoFisher Scientific). Data were evaluated as percent of the control wells: % Inhibition=(1−(Treated−Initial)/(Control−Initial))×100. where Treated: mean cell number of wells after compound treatment for 72 h

-   -   Control: mean cell number of wells without compound treatment         for 72 h     -   Initial: mean cell number of wells before compound treatment

-   IC₅₀ values were calculated by regression analysis of the     log-concentration-inhibition curves.

-   Given the above assays, the compounds of formula (I) of the     invention resulted to possess a remarkable antiproliferative     activity, as shown in Table 3.
